I dunno but every 2 hours or so I will get a glitch effect graphically (e.g. Adobe Illustrator 2017)...then some 2nd/3rd party apps will freeze (e.g. Scrambler 1.3).
I just realized that if I have my MacBook Pro 15 2016 connected to an external display, Final Cut Pro X refuses to load. When I disconnect, it works just fine. Work around is to load it first, and then plug into the display. LAME
